The Simpson Strong-Tie ECCQ78SDS2.5 is a heavy-duty 6-3/4" beam, 8x post end column cap engineered to deliver reliable column-to-beam connections in end-of-beam wood construction applications. Fabricated from 3-gauge steel with a Simpson Strong-Tie Gray paint finish, this column cap features an extended bearing seat that distributes load from the beam across a greater surface area beyond the side of the column. Supplied complete with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws for both beam and post attachment, the ECCQ78SDS2.5 offers fast, high-strength installation with a low-profile result suited to demanding structural applications.
Key Features
- Extended seat bearing surface distributes load from the beam and provides additional support at the connection point
- Strong-Drive SDS Heavy-Duty Connector screws attach to a greater net section area of the column compared to standard bolt attachment
- SDS screws provide a lower profile than standard through bolts
- Certified welds for confidence in strength and load performance
- Increased uplift load values for earthquake or wind loading conditions
- Diamond holes allow for temporary fastening during installation
- Manufactured from 3-gauge steel for exceptional structural integrity
- Simpson Strong-Tie Gray paint finish for corrosion resistance
- Made in the United States

Frequently Asked Questions
- What beam and post sizes is the ECCQ78SDS2.5 designed to fit?
- The ECCQ78SDS2.5 is designed for use with a 6-3/4 in. wide beam and an 8x post. Its key dimensions include a W1 of 6-7/8 in., a W2 of 7-1/2 in., a length of 8-1/2 in., and a height of 7 in., making it suitable for heavy timber end-of-beam column connections.
- What fasteners are included with the ECCQ78SDS2.5, and why are they preferred over standard bolts?
- The ECCQ78SDS2.5 comes supplied with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws for both beam and post attachment. These screws are preferred over standard through bolts because they attach to a greater net section area of the column and provide a lower-profile installation result while still delivering high-strength performance.
- What material and finish is used on the ECCQ78SDS2.5?
- The ECCQ78SDS2.5 is fabricated from 3-gauge steel and features a Simpson Strong-Tie Gray paint finish, which provides corrosion resistance for demanding structural applications.
- Is the ECCQ78SDS2.5 suitable for use in areas subject to high wind or seismic activity?
- Yes. The ECCQ78SDS2.5 features increased uplift load values specifically designed to meet the demands of earthquake or wind loading conditions, making it appropriate for use in structurally demanding environments where enhanced uplift resistance is required.
